Eco-Memory is the classic memory game where the goal is to find matching pairs of cards. The cards represent habitats, organisms, and cultural entities of ecosystems like the Boreal Forest, Coral Reef, Deciduous Forest, Desert, Ice, Intertidal Zone, Rainforest, Surface Zone, Tundra, and Wetland. The game includes a small synopsis of the organisms, the cultural entities, and the habitats themselves. The synopsis is available through an "About" button that you may click after finding a matching pair of cards.

JavaScript Scrollbar to Top is an object that adds scrollbars to the top and the bottom of wide elements that do not fit horizontally inside Web page container elements. It takes a given Web page element and inserts it within a container element with an automatic scrollbar that appears if the contained element does not fit horizontally. Another scrollbar shows at the top of the element, so the user can scroll it without having to use the scrollbar at the bottom. The wide element may also get the keyboard focus, so the user may scroll it using the arrow keys.
